Which of the following best describes "evenness" in an ecosystem?

• The total number of species present

• How balanced the individual organisms are among different species

• The amount of equal energy each species receives each trophic level

• The number of symbiotic relationships in the ecosystem

Why is high species richness generally considered a good sign of ecosystem health?

• It means there are more predators within an ecosystem

• It is correlated with higher ecosystem stability and resource availability

• It means there are fewer plants that compete for soil nutrients

• It indicates a lack of competition within an ecosystem which preserves biodiversity

What does the diagram of the bottleneck event illustrate about the population's genetic makeup after the event?

• The population has more genetic diversity than before

• The population has the same genetic diversity as before

• The population has less genetic diversity than before

• The population's genetic diversity is unrelated to the event
